By the employment of the form of holder illustrated in Flgures 4 and 5, the gripp g of the and of the covered electrode is greatly facilitated and the fulcrum member 12 assists in leading the welding current to the bare end of the coated pencil. From the above description it will be apparent that the holder is exceedingly light and accordingly easy to manipulate, may be manufactin'ed at a relatively low cost, and is particularly useful due to the facility with which the electrode v may be placed between the gripping Jaws.

An electrode holder comprising electrode gri ping iaw's and a fulcrum member adjacent the ends of said jaws provided with a cupped portion adapted to terminally engage an electrode and about which the electrode may be rotated and forced between said jaws. I i
